Michael Clarke was diplomatic as the divisive issue of pitch doctoring reared its head, with revelations the curator for the second Test in South Africa is at the beck and call of the Proteas.

Shane Watson is expected to remain sidelined as Australia take an unchanged XI into the match at Port Elizabeth, which will be played in contrived conditions starting on Thursday.

It is understood Proteas coach Russell Domingo was disappointed with the bouncy Centurion surface for the first Test, which Mitchell Johnson took advantage of to claim career-best match figures of 12 for 127 and guide Australia to a 281-run victory.

Another defeat for Domingo and South Africa captain Graeme Smith would trigger the ignominy of the nation's first Test series loss since 2009.

The pair have enlisted the help of St George's Park curator Adrian Carter to enhance their hopes of avoiding that result.

If the wicket stays like it is today it will be a three-dayer, especially with two fantastic bowling attacks.

"I had a chat to the groundsman. At the moment the grass is 8mm high," Michael Clarke said of the strip.

"He said he's going to speak to their captain and coach before he makes a decision (on what to do with the grass).

"Hopefully it does (stay as is).

"If the wicket stays like it is today it will be a three-dayer, especially with two fantastic bowling attacks."

But Smith rejected claims the Proteas made any demands.

"One thing I've learned is that when you ask for things you generally don't get them," he said.

Carter confirmed to ESPNcricinfo that he had thoughts on what to do with a "furry and green" surface that scared him, but would not act without Domingo and Smith's approval.

Clarke was not keen to cry foul about Carter's kowtowing.

"It doesn't bother me, that's a big part of playing international cricket, you travel the world and play in different conditions," the Australia captain said.

"It's a big part our game that the captain, especially, can communicate with the groundsman in his home country and produce the wicket that is best suited to their team."

Smith, Domingo and his assistant coaches inspected the pitch and had lengthy discussions with Carter before South Africa started training on Tuesday.

A similar chain of command exists at many cricket grounds, however the process is usually not as overt or explicitly admitted to.

England captain Alastair Cook put Australian noses out of joint in the 2013 Ashes when he suggested pitch doctoring was "what home advantage is".

Carter will find it hard to create a strip that makes Johnson easy to play.
